IBERTHOLD W. BLAUERT, 0F MARYSVHJLE, CALIFORNIA.

Application filed July 30,

T 0 all whom it may concern Be it known that I, BERTHOLD W. BLAUERT, .a citizen of the United States, residing at Marysville in the county of Yuba and State of California, have invented certain new and useful Improvements in Tablettes for Chairs, of which the following is a specification, reference being had to the accompanying drawings.

The present invention has for its purpose the provision of an improved device of this character for writing, drawing, reading, for

dressmaking, or for the support of any objects or articles, such as dishes or the like,

when employed for use'in connection with any kind of chair, particularly chairs having arm rests.

Another purpose is the provision of a tablette for the above purposes, adapted for use, in a horizontal plane, or a plane upwardly at an angle to the arm rest of the chair, and when used in a horizontal plane dressmaking, and writing paraphernalia and similar articles, such as dishes and the like may be supported, and when disposed on an upwardly'inclined plane, adapted for supporting articles of readingor drawing materials and instruments. In the latter case, the drafting or reading articles are supported, so as to avoid the person from leaning over, and furthermore the tablette may be adjusted toward and fromthe person,

so that the party may assume a straight position substantially fully incontact'with the back of the chair, thereby enabling drafting or reading to be conducted with ease and I comfort.

for the tablette, one or both of which'may be adjustable, so as to accommodate arm rests of chairs of different sizes.

" Additionally the invention aims to provide supports having clips or attaching devices,

and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a view in perspective showing the improved tablette as applied to the arm rest of a chair, the tablette being disposed in a slightly inclined plane and adapted for use in drafting;

Figure 2 is a view in perspective showing a tablette supported on the arm rest in a horizontal position, whereby the tablette may be used for writing and the'like;

Figure 3 is a sectional view on line 3-3 of Figure 1, showing how the supports engage the arm rests;

' Figure at is a sectional view showing how the supports engage the arm rests for supporting the tablette in a horizontal position.

Figure 5 is a bottom plan view, showing the construction of the stationary and adjustable support or slide.

Figure 6 is an enlarged detail view of the adjustable support and slide; and

Figure 7 is a sectional view on line 7-7 of Figure 5.

Referring to the drawings, 1 designates a tablette or table, which may be constructed of any suitable material, either light sheet metal, such as aluminum, or wood, and which may be any suitable or convenient size as the needs demand.

The upper surface of the tablette adjacent the longitudinal edge nearest the person using the tablette is provided with a ledge 2, which acts to prevent articles of reading, drafting paraphernalia or the. like from slipping off the tablette or table,particularly when it is in an inclined plane.

The under face of the'tablette adjacent the ledge is provided with a groove or channel 3, in which a slide 4 is mounted.

Secured to the under face of the tablette adjacent one end is a stationary support 5 which angle plate overlies oneedge of the support 5, so that the lateral projecting part 7 of the plate may engage under the arm rest of the chair. Alsosecured to the support'5 is a metal strip or plate 8, located between the angle plate 6 and the edge of the tablette, and projects laterally from the support, so as to engage the upper surface of the armrest. In fact the arm rest engages between the two plates, though they are offset from each other, and therefore acts to support the tablette firmly in position.

Secured to and movable with the slide 4 1s a second support 9, which is provided with arm rest engaging plates similar to the platesfi and 8, therefore designated bythe same characters, and are adapted to engage above and below the opposite arm rest. When applying the tablette to the arm rests of the chair, the stationary support 5 is ar ranged adjacent the right handjarm rest,' so that the plates 6 and 8 may ei'i'gage above and below the rest, after which the movable support 9 is adjusted, by moving the slide 4 in its. channel or groove, until the edge of the support 9 contacts with the edge of the left arm rest, with the other plates 6 and 8 overlying the'upper and lower faces ofthe arm rests.

Sheet metal plates 10 are secured to the under surface of the tablette adjacent its opposite ends and overlie the ends of the groove or channel, and secured to the-under face of the tablette and overlying the plates 10 are strips of felt 11., which overlie the edge of the tablette nearest the person using the same, so as to engage upon the arm rests, and prevent injuring or marring' the finish of the chair. j

A pair of strips 12 and 13 are secured to the under surface of the tablette in spaced relation, and secured to and connecting these strips 'is' a guide piece 14, between which and the under surface of the tablette the "movable support 9 (which is extended sufficiently) engages, so as to-assist in bolding the'support and'guiding the same, and to insure rigidity, particularly when the tablette or table'is disposedon an inclined plane, as shown in Figure 1.

IVhen the tablette or table is disposed as shown in Figure 1, the stationary support 5 is arranged adjacent the right hand arm rest, so that the arm rest will engage between the lateral portion of the plate or strip 8,

and the'edge of the tablette nearest the person using the same, then the movable support is adjusted, so that the left hand arm rest may engage the oppositeplate or strip 8 and the edge of the tablette or table. The slide is freely movable in its channel, though there is a sufiicient amount of friction, to enable the same to remainin its different adjusted positions, therebypreventing the tablette or table from displacement.

.l/Vhen the tablette is disposed as in Figure 1, it may be used for drafting purposes, or for reading purposes and the like, and when the tablette is arranged as in Figure 2, it may support writing or dressmaking material, and similar articles, or support dishes and the like. This improved tablette or table may be manipulated and easily applied by any person, and the adjustable supports are most important and essential, thereby making it possible to attach the tablette or table to arm rests of chairs ofdiiferent sizes.

The invention having been set forth, what is claimed as being new and useful is: N

1. As an article of manufacture, a tab lette adapted to engage from onearm rest to another of a chair, a stationary support secured on the under surface of the tablette near one end, a second support mounted for longitudinal adjustment on the under surfaceof the tablette, and means carried by said supports for engaging with the upper and lower faces of the arm rests of a chair, thereby supporting the tablette in position thereon, a slide for carryingthe adjustable. support, and means cooperating with the adjustable support to insure. rigidity between the support and thetablett'e;

2, In a tablette for chairs, a body, a stationary support on'the under surfaceof the body,'to engage one arm rest of the chair, a.

second support adjustably mounted on the.

body to engage the opposite arm rest, means on said supports between which and one edge of the-tablette the arm rests engage for supporting the tablette in an inclined plane. Y 3. In a tablette for chairs, a body, a stationary support on the under surface of the body, to engage one arm rest of the chair, a secondsuppor't mounted for longitudinal adjustment on the body to engage theopposite arm rest, meanson said supports be tween which and one edge of the tablette the arm rests engage for supporting the tablette in an inclined plane, and means to insure rigidity between the adjustable support'and the'tablette. V

v 4:. In a tablette for arm chairs, a tablette body having a ledgeadjacent one edge to prevent articles from sliding off thetablette body and to support books, a guide on the under surface of the tablette body, a member in said guide and carrying a supp'ort,a stationary support on the under surface of the tablette body near its opposite end, means to insure rigidity between the movable support and the-body, plates connected to corresponding ends of said supports andengage I V ing aboveand below the arm rests of the chair to support the tablette body in position.

5. In a tablette for chairs, a tablette body, a stationary support on the under surface of the body, a second support mounted for longitudinal adjustment on the under surface ofthe body, said supports adapted to engage the inner faces of the arm rests, and means extending laterally in opposite directions from the supports and between which and one edge of the tablette body the arm rests engage, thereby supporting the body upon an inclined plane upwardly from the arm rests.

6. In a tablette for chairs, a tablette body, a stationary support on the under surface of the body, a second support mounted for longitudinal adjustment on the under surface of the body said supports adapted to engage the inner faces of the arm rests, and

means extending laterally in opposite directions from the supports and between which and one edge of the tablette body the arm rests engage, thereby supporting the body upon an inclined plane upwardly from the arm rests, said body having a guide, a slide movable with the adjustable support and engaging said guide, a holding cleat for one end of the adjustable support, said holding cleat together with the slide and guide insuring rigidity for the adjustable support.

In testimony whereof I hereunto aflix my signature.
